      iterator begin ();
const_iterator begin () const;

Return iterator to beginning

Returns an iterator referring to the first element in the list container.

Parameters

// list::begin
#include <iostream>
#include <list>
using namespace std;

int main ()
{
  int myints[] = {75,23,65,42,13};
  list<int> mylist (myints,myints+5);

  list<int>::iterator it;

  cout << "mylist contains:";
  for ( it=mylist.begin() ; it != mylist.end(); it++ )
    cout << " " << *it;

  cout << endl;

  return 0;
}


Output:
mylist contains: 75 23 65 42 13


Complexity

Constant.
